How do prevent and reduce pump cavitation?
Method 1 to reduce cavitation of water pump: improve the anti-cavitation performance of the water pump
Reduce the necessary NPSH
(1)Water pump with double suction impeller. NPSH of double suction pump δ HC ratio NPSH of single-stage single-suction pump δ HC is small. For pumps with the same speed n and flow Q, try to use double suction impellers.
(2)Appropriately increase the impeller inlet diameter and blade inlet width. When the impeller inlet diameter and blade inlet width increase, the impeller inlet speed and relative speed decrease, which shows that the critical NPSH of the pump decreases. But at this time, the area of the leakage reduction ring at the impeller inlet increases, the leakage increases, and the volumetric efficiency of the pump will decrease.
(3)Inducer is added in front of the impeller. The inducer is set in front of the centrifugal pump impeller. The inducer operates with the leaves of the pump, and the pressure wheel generated by it operates together after coaxial assembly. The pressure generated by it pressurizes the impeller inlet and improves the anti-cavitation performance of the pump. However, the performance of the water pump will be unstable if the inducer is added. Therefore, it needs further exploration and research.
To reduce the damage of cavitation to the flow passage parts of the water pump and prolong its service life, materials with strong cavitation resistance are often selected. For example, cast manganese, bronze, stainless steel, alloy steel, and other materials are used to cast the impeller; Or coat the surface of flow passage parts with polymer or laser spraying to resist cavitation damage. In addition, finishing the surface of flow passage parts to improve their smoothness can also reduce the harm of cavitation.
Method 2 to reduce the cavitation of the water pump: improve the anti-cavitation ability of the water inlet device
NPSH is closely related to the water inlet device and pipeline system, so a good water inlet device should be designed to improve the NPSH at the pump inlet as much as possible to meet the requirements of dynamic pressure drop in the pump.
(1)Reasonably determine the suction height of the water pump. Since the water pump generally operates under nondesign conditions, various working conditions that may be encountered in the work of the water pump should be fully considered, and the determined water absorption height should meet the requirements of water absorption performance of the water pump under any working condition.
(2)Select a reasonable water inlet pipe. Try to reduce the length of the inlet pipe and unnecessary pipe accessories, and appropriately increase the inlet pipe diameter to reduce the hydraulic loss of the inlet pipe and improve the NPSH at the pump inlet. For large flow pumps, the flow velocity and pressure in the inlet pipe should be evenly distributed as far as possible, which will help to prevent cavitation.
(3) Well-designed intake tank. A good water inlet pool can not only reduce the drop of water level in the pool and reduce the resistance coefficient of the inlet pipe orifice but also make the water surface in the pool stable without vortex. It can prevent air from entering the pump and prevent cavitation from occurring prematurely.
Measures that can be taken in operation management
(1)Try to make the water pump operate in the design condition. According to the specific conditions of the pump station, adjusting measures such as valve change, speed change, and angle change can be adopted to prevent the operating condition of the pump from deviating too far from the design condition.
(2)Control the extent that the actual speed of the water pump is higher than the design speed. Since the necessary NPSH is proportional to the square of the speed, when the speed is too high, not only the necessary NPSH will be greatly increased, but also the effective NPSH will be reduced.
(3)When cavitation occurs in the operation of the water pump, the method of filling a small amount of air or high-pressure water into the water inlet of the water pump can be used to reduce or avoid the harm of cavitation.
Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products, and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps. Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting, and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders, and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps, i.e. pump driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables), and a starting protection de
